Entry
Description
Interface name
As stated
Address
The IPv6 address of the interface.
DR
The IPv6 address of the Designated Router (DR).
Hello period
When PIM is enabled on an interface or a router first starts, the Hello Timer of that interface is set to a random value between 0 and Triggered_Hello_Delay. This prevents synchronization of Hello messages if multiple routers are powered on simultaneously. After the initial randomized interval, Hello messages MUST be sent every Hello_Period seconds. The Hello Timer should not be reset except when it expires.
Next Hello
The time period before the next Hello is sent.
Triggered Hello period
A per-interface Hello Timer (HT(I)) is used to trigger sending Hello messages on each active interface. When PIM is enabled on an interface or a router first starts, the Hello Timer of that interface is set to a random value between 0 and Triggered_Hello_Delay.
Propagation delay
The Propagation Delay field of the LAN Prune Delay option (if present) in the Hello message.
ECMP REDIRECT
Whether Equal-Cost Multiple-Path (ECMP) is allowed and on which bundle.
Secondary address
As stated.
